The goat's rue grows successfully in most types of soils, but will grow with maximum potential if grown under ideal soil conditions. The herb grows optimally at sites with a good exposure to sunlight and prefers deep moist soils. However, the goat's rue can also successfully grow in sites with light shade.

Goat's rue is a leguminous plant of the pea family, this species and most plants in the genus have a symbiotic relationship with certain strains of bacteria which dwell in the soil. The bacteria aid by fixing atmospheric nitrogen and can be found in nodules on the roots of the plants. As nitrogen is a precious nutrient, this relationship is very successful for both bacterium and herb. The growing plant utilizes the majority of the nitrogen fixed by the bacteria present in the nodules; however, some of this fixed nitrogen can be utilized by neighboring plants in the site. The goat's rue is normally propagated using seeds that have been soaked in some warm water for twelve hours before sowing. The sowing of seeds is usually carried out during the spring or the fall on a cold frame. Seeds that have been sown during the spring may take time to germinate, the germination time of such spring sown seeds can be improved by giving them a period of cold stratification. Once the seedlings grow large enough to handle by hand, each single seedling is pricked out into individual pots and theses are then plant out in the summer at the permanent positions out doors. Another option, if to sow seeds outdoors in situ from mid to late spring - this is possible only, when the supply of seeds is not a problem. The seedlings undergo division in spring or in the fall. Seedlings that are found in larger clumps may be replanted directly into the permanent positions they will occupy. However, it may be best grow the smaller clumps in pots on a cold frame till they have begun to rooting well in the soil. These can then be plant out of doors in the spring at the permanent sites.

From Francisco Lubbert
About 4 months ago I gave goat's rue to a 70 year old neighbor suffering from type II diabetes. He got much better on his glucose levels, then something called my attention: he mentioned it had solved several problems, like pains or uneasiness and frequent night urinating, simply put he felt as never before. Then talking he also mentioned having prostate problems, which makes me think the goat's rue might have had a good effect on that. Too bad I cannot find anything confirming it on the web.
